Can Bed Bugs Live on Cats?

Can Bed Bugs Live on Cats?

Short answer: no — bed bugs do not live on cats. They will feed on cats (and dogs) if they get the chance, but they do not stay on your pet or nest in fur. Bed bugs are flat, furniture-hiding insects adapted to crawl out at night, feed briefly, and retreat to cracks and seams near where you and your pet sleep.

We understand how worrying it is to see your cat scratching and to wonder if they’re carrying bed bugs around the home. As heat-treatment specialists, ThermoPest helps households and businesses resolve bed bug problems quickly, safely, and decisively, without exposing pets to unnecessary chemicals.

What people believe vs reality

• Belief: Bed bugs live like fleas in a pet’s fur.
  Reality: Bed bugs don’t cling to fur or remain on the host. They lack the claws and body shape to live on animals. After feeding, they return to nearby harbourages (furniture joints, skirting boards, mattresses, pet beds).
• Belief: If my cat is bitten, the infestation is on the cat.
  Reality: Bites simply mean hungry bugs are present in the environment. The source is almost always in rooms, furniture, or belongings rather than on the animal.
• Belief: A flea collar or pet spray will solve bed bugs.
  Reality: Flea products are not designed for bed bugs and won’t address eggs or hidden harbourages.

Science-backed facts about bed bugs and pets

• Host preference: Bed bugs prefer human blood but are opportunistic and will feed on cats if close and accessible.
• Where they hide: Seams of mattresses, bed frames, bedside furniture, skirting boards, soft furnishings, and pet bedding seams or zips.
• No disease transmission: Bed bugs are not known to transmit disease to pets or people, though bites can cause itching and secondary infection from scratching.
• Egg resilience: Eggs are glued to rough surfaces and are the most resilient life stage. Lethal heat must reach them fully. See what researchers and professionals mean by what temperature kills bed bugs.

Common mistakes when pets are involved

• Using flea bombs or DIY sprays: These rarely reach hidden harbourages and can disperse bed bugs deeper into the property. Many products are not pet-safe when misapplied.
• Only treating the cat bed: Pet bedding is a frequent harbourage, but the source is typically nearby furniture and room edges. Treating one item leaves the infestation intact.
• Spot steaming without validation: Surface steam may not hold lethal temperature long enough in deeper seams, leaving eggs viable.

Practical, pet‑safe steps you can do now

• Inspect and launder: Check seams and zips of your cat’s bedding and soft furnishings. Wash on a hot cycle (60°C) and tumble-dry on high heat if care labels allow.
• Vacuum thoroughly: Use a crevice tool around skirting boards, bed frames, sofa joints, and pet areas. Bag and bin the vacuum contents promptly.
• Reduce clutter: Fewer hiding places makes monitoring and treatment more effective.
• Prepare for professional heat: Read our guidance on preparing your home for treatment so rooms and pet items are ready for effective, even heating.

Why heat treatment is the superior solution

Chemicals struggle with resistant populations and hidden eggs. Professional heat penetrates deeply and kills every life stage in one structured visit when done correctly.

• Cold spots addressed: Bed bugs survive if any cool refuges remain. Our technicians design air movement to eliminate cold spots in bed frames, furniture voids, and pet bedding seams.
• Sustained lethal temperature: It’s not just peak heat that matters — it’s holding lethal temperatures long enough for heat to conduct into materials and eggs. Learn more about our bed bug heat treatment process.
• Sensors and monitoring: We place multiple temperature probes in the most challenging locations to verify that lethal thresholds are achieved and maintained.
• All life stages killed: Adults, nymphs, and eggs are brought above lethal temperature throughout the treatment zone, something chemicals often fail to achieve in one pass.

ThermoPest expertise

ThermoPest specialises in bed bug heat treatment for homes and also provides commercial heat treatment for hotels and landlords, where rapid, discreet resolution and minimal downtime are essential. Our teams handle delicate items, pet areas, and complex furnishings with care, validating temperatures so no life stage survives. After treatment, we’ll advise how to protect against re‑introduction and how to monitor effectively over the following weeks.

FAQ’S

Question: Can bed bugs live on cats or in their fur?

Answer: No. Bed bugs are not adapted to live on animals; they lack the claws and body shape to cling to fur and prefer to hide in furniture and cracks nearby. They may feed on a resting cat and then return to harbourages rather than remaining on the animal. This is why treating the environment is crucial. In professional practice, we inspect and heat the room and furnishings rather than the pet.

Question: Could my cat bring bed bugs into the house?

Answer: It’s possible for bed bugs to hitchhike on pet bedding, carriers, or blankets, but clothing, luggage, and second‑hand furniture are more common vehicles. If you’ve recently travelled or had visitors, consider re‑introduction rather than a treatment failure. Launder soft items on hot cycles and isolate suspect items in sealed bags before washing. In professional practice, we pair treatment with sensible hygiene to reduce re‑introduction risks.

Question: Do flea treatments or pet sprays get rid of bed bugs?

Answer: No. Flea products are not designed or approved for bed bugs, and applying insecticides to pets for bed bugs is unsafe and ineffective. Bed bug eggs are particularly resilient, and hidden harbourages shield bugs from casual sprays. Use heat: wash and tumble‑dry pet bedding hot (60°C if allowed) and schedule whole‑room heat for full control. In professional practice, we rely on validated heat rather than pet‑applied chemicals.

Question: How do I confirm bed bugs are gone after treatment?

Answer: Confirmation comes from no new bites or sightings and from passive devices showing no activity over several weeks. Place interceptors or traps and monitor your property after treatment to catch any missed or re‑introduced bugs. Remember that a single bug brought home later is re‑introduction, not resurgence from eggs if heat was verified. In professional practice, we use sensors during heat and advise post‑treatment monitoring to validate success.

Question: Do I need to throw away my cat’s bed and toys?

Answer: Usually not. Most soft items can be made safe by washing at 60°C and tumble‑drying hot, or by including them in a professional heat treatment so heat penetrates seams and fills. Focus on seams, zips, and stuffing edges where eggs may be glued. If an item can’t tolerate heat, isolate it in a sealed bag until it can be treated or replaced. In professional practice, we prioritise heat over disposal to save possessions.
